CBI/CGI Technical Reference

Available options are:

•Boot Only - Only the removable-media drive designated as the boot device is treated as a hard disk drive. This is the default option.

•All Disks - All removable-media drives supported by the AIC-7880 BIOS are treated as hard drives. This setting has no effect on drives under NetWare, because NetWare automatically supports removable-media drives as fixed disks.

•Disabled - No removable-media drives running under DOS are treated as hard disk drives. In this situation, driver software is needed, because the drives are not controlled by the BIOS.

Extended BIOS Translation for DOS Drives > 1 GByte

All current versions of MS-DOS are limited to 1024 cylinders per drive. The standard translation scheme for SCSI host adapters, using 64 heads and 32 sectors, provides a maximum accessible capacity of 1 GByte. To support disk drives larger than 1 GByte, the AIC-7880 BIOS includes an extended translation scheme that supports disk drives as large as 8 GBytes under MS-DOS.

This option is not available if the Host Adapter BIOS option is set to Disabled. The default for this option is Enabled and should not be changed. With extended translation enabled, drives handled by the AIC-7880 BIOS use extended translation if their formatted capacity is greater than 1 GByte, and drives smaller than 1 GByte use standard translation.

_______________________________________________________________________

NOTE: If you decide to change the translation scheme, be sure to back up the disk drives first. All data is erased when you change from one translation scheme to another.

_______________________________________________________________________

When you partition a disk larger than 1 GByte, use the MS-DOS fdisk utility as you normally would. Because the cylinder size increases up to 8MB under extended trans- lation, the partition size you choose must be a multiple of 8MB. If you request a size that is not a multiple of 8MB, fdisk rounds up to the nearest whole multiple of 8MB.

Available options are:

Enabled

Disabled

Display <Ctrl-A> Message During BIOS Initialization

This option has no effect since the configuration utility is invoked using the cfg7880.exe program.

Multiple LUN Support

This option allows the BIOS to support multiple logical units. Set this option to Enabled if any devices have multiple logical units.
